Precision livestock nutrition uses individual animal data to optimise feed allocation. This approach can significantly improve welfare by preventing metabolic disease, supporting appropriate body condition, and reducing nutritional stress.
Nutritional welfare for dairy cattle is complex because cows in high production systems are routinely pushed to the edge of their metabolic capacity. SARA, ketosis, milk fever, and displaced abomasum are all partially or fully nutritionally mediated conditions that cause significant suffering. Precision nutrition reduces these risks by tailoring feed to individual needs rather than applying group averages that leave some cows under or over-nourished. The welfare benefit of precision nutrition is greatest during the transition period around calving, when metabolic demands change most rapidly. Technology that monitors individual intake and metabolic status enables earlier detection and correction of nutritional problems before clinical disease develops.
